#potential problem with this plot is that by plotting the ratio, a ratio of 0.5 (50% decrease) may be equivalent to a ratio of 2 (100% increase)...? Is this plot disproportionately inflating positive values? I have also now removed the scale limits so that every data point is shown.

anova(recovmod3)# symbiont recovery was significantly differnet between species (recovery days * symbiont density interaction), with ofav p=0.00556 and ssid p=6.48e-06 recovering more than mcav for a given amount of recovery (likely indicative of the delay in symbiont recovery seen in mcav). There was also a significant interaction between initial symbiont genus and recovery days p=2.00e-05, with corals initially not hosting Durusdinium recovering more with a given amount of recovery.

###UPDATE FOR ROSS: The predicted values are based of a model which controls for pre-heat stress proportion durusdinium (rather than proportion durusdinium at the previous timepoint). Making 'timepoint' an integer rather than a factor in the model also changed things. Would like to perform stats on the interaction effect on shuffling between timepoint and species, but unsure how since mcav fitted to a separate model. The '2-month recovery' points are very slightly differnet from those in the bleached Vs control shuffling plot, but I think this is indicative of shuffling at each timepoint being linked to each coral (rather than averaged within each species) for these predicted values, arther than a mistake in the code.
